IMPRovMENT 1N WIND-WHEELS.

The Schedule referred to in these Letters Patentand making part of thesame.

To all whom it may concern v i Be it known that I, CHARLES MAHLER, ofthe city declare the following description and accompanying drawingsaresucient to enable any person skilled in the art or science to whichit most nearly appertains to make and use-my said invention orimprovements, wit-hout 4further invention or experiment.

My invention relates to an improved wind-mill, which may also, whendivested of aiportion of its regulating parts, be employed as i awater-wheel for driving ma chnery, or as a propeller-wheel for vesselsfloating in the water; and i l It consists in providing transverse slotsin the vanes sides of the arm may be varied las desired.

mounted above the mill-frame, so as to operate the devices forcontrolling the speed of the wheel.

In order.v to more .fully illustrate and explain my invention, referenceis had to the accompanying drawings, forming a part` of thisspeoifcation,in which- A A represent two vertical' posts, having theplate any other suitable flame can be used. p

C is 4the vertical shaft which supports the mill, and

D, between the two posts A A, and passing through Secured upon' thelupper end of the upright shaft C is a box, E, which may have its sidesentirely closed or.,a portion left'open, as shown, for adjusting anyranged.

Passing through the sides of this box, at right anextend a considerabledistance from theA sides of the box on each side, and have secured upontheir op` posite ends the vanes or` sails G, the' two opposite vanes oneach shaft heilig placed at right angles tol shaft. .i

.The vanes are secured'upon lthe opposite ends of the shaftsor spindlesin such a manner that the great upon the lower part, where` there ist-he greatest leverage, thus feathering the opposite vanes, so as tocause Transverse slots, a, serve to render the vanes adjustable in orderto vary the weight.

Inside the box the spindles have an elongated lug or projection, b,formed on them, which serves to stop the revolution of the shaftwhcuitturns to the proper position in feath'ering the vanes.

' Secured to the sides of the box on each side of the spindles, and withtheir widest end uppermost, are, `wedge-shaped blocks, 1, having theirinclined sides facing the spindles. A block, J, similar in form, isplaced with its narrow end uppermost, so that both inclined surfaceswill lie in contact, the two blocks forming a square.

The inclined surfaces of there blocks are corrugated, as shown, in orderthat when the lug 7J on the spindle strikes the block J the corrugationswill lock the two together, and prevent the block Ifrom slipi ping. l

A suitable guard, d, is arranged beneath the sliding block I, so asvtoprevent it from being displaced.

.Extending upward from the top of the box is a spindle, K, to the upperend of which are attached four arms ot' a governor, L, each pair beingconnected with the movable blockJ ot' each vane-shaft by means of therodsf.

These governors prevent the wheel from running at too high'avrate ofspeed, should the wind blow very strong, by raising the blocks J, andthus preventing the vane-shafts from tuming suiicentlyto allow the windto strike the full face ofthe vane.

When in operation, the vanes as they come around against the wind liehorizontally, so as to present no smface for it to act against, whilethe one on .the opposit-e end of the shaft stands vertically, receivingthe full force ofthe wind until the former comes to a po` sition whereit Jcatches the wind, when, on account of the weight being ou the `underside of the shaft, it will turn until the projection 1b strikes the`block J on the opposite side, changing the position of the two oppositevanes.

This operation is'cont-inued as long as the wind is steady; but shouldit increase to a gale, the arms of the governors will y out and raisethe block J, thus causing'the vanes to stand at .an angle to theuvind,in

which position'it has less power against them, and

consequently the speed is reguiated. The wheel above described can alsohe mounted vertically, in which case the governors would be, dispensedwith, the vanes feathering automatically, owingto their peculiarconstruction.

, When used 'as a water-wheel or propeller for vessels, the wheel willkbe entirely submerged, the same action taking place in the water as`previously def scribed in the case of a wind-mill.

Havingr thus describedmy invention,

What I c1aim,and desire to secure by Letters Patent, 1s-

1. Regulating the speed of the wheel by means of the two inclined hloeksI and J, whose inclosed surfaces are corrugated, as described, and the`lug or projection b on the shait F, in combination with the governor L,substantially as herein specified.

v 2. The slots a in the valles G, whereby the relative widths of thepartson opposite sides of the arms are made variable, substantially asand for the purpose set forth.

/ In witness whereof I have hereunto set my hand and seal.
